Abstract (en)
To continuously detect a position of a rotor of a motor having the rotor formed with a plurality of magnetic poles by permanent magnets without using an expensive encoder, the rotor position is continuously detected by arranging a rotor formed with, for example, 8 poles by permanent magnets, a stator having, for example, 9 slots of magnetic legs opposed to the rotor, an analog type Hall element arranged at a position opposed to the magnetic poles of the rotor, an analog type Hall sensor for outputting an analog magnetism detecting signal the phase of which is shifted by 90 DEG from that of the analog type Hall sensor or a digital type Hall sensor for out-putting a digital magnetism detecting signal comprising a binary signal and comparing the magnetism detecting signals having different phases by 90 DEG . <IMAGE> <IMAGE>
